An arrangement is provided for controlling the coolant temperature in a coolant circulating system of an internal-combustion engine, such as in a motor vehicle, containing a thermostatic valve that controls the coolant flow from the internal-combustion engine through a direct return flow means and/or through a heat exchanger back to the internal-combustion engine, and containing a thermostatic working element having a housing carrying a valve disk of a valve controlling coolant flow to the heat exchanger, and having a working piston extendable under heat and being supported at a counterbearing. The working piston and the counterbearing form an adjusting mechanism, and a control element is connected to the working piston or the counterbearing which forces the working piston into an adjusted position.
